Determine whether each system is LTI, causal and/or stable and with or without memory. Justify answers.

a) y[n + 1] + 4y[n] = 3x[n + 1] - x[n]

b) y[n] = nx[2n]

Solutions

Expert Solution

  • CAUSAL SYSTEM:- System output is independent of future values of input.
  • STABLE SYSTEM:-System output should be BIBO at each and every instant of time.
  • SYSTEM WITH AND WITHOUT MEMORY:-Output is depended only on the present input.
